Patented Aug. 25, 1953 UNITED STATES PATENT o-FF IiCE removably attaching the legsof-the-trestle to the horizontal supporting rail.

Itis one of the objects of thisinvention to provide a bracket movably positioning the legs in tion tothe rail.

It is another object of this invention to provide which the legs are may be readily compensated for:

It is a further object of this invention to provide abracket of and" disassemble the various parts of the trestle or-saw horse.

The foregoing as well as other objects will be made more'apparentas this description proceeds, especiallywhenconsidered in connection with the accompanying drawing, wherein:

Figure 1 is a: side elevational view of a trestle or saw horse having bracketsembodying the features of thisinvention;

Figure 2 isa perspective view of one of the brackets showing the associatedparts of the saw horse in broken lines;

Figure 3 is a sectionalvi 3+3of'Figure 1; and

Figure 4 is a plan view of the bracket shown in Figure 2.

Referring now more in detail to the drawing, it will be notedthat the reference character l w" taken on the line In thecpresent instancetherail H and supportdetachably secured in assembled the brackets I3-which cooperate to rigidly hold the several partsof the trestle in body member M having standing-flanges I6 atopposite ends of the. base.

A pair: of U-shaped straps 19 arepositioned at opposite sides of the body member Wand open 14', and the base portions respectively disposed in sides. of the legs. If desired suitable blocks 2'5 may bet'weldedtor otherwise washer 21is supported on each stud 26 at the outer side of the adjacent clamp, and a fastener, preferably in the form of a wing nut 29, is threaded on each stud to coact with the washers in securing the clamps 22 in place.

Inasmuch as the top flanges 24 on the clamps 22 overlie the upper ends of the adjacent pair of legs l2,.it follows'that movement of the clamps vertically relative to the straps renders it possible to adjust the effective length of the legs. Also. since the clamps 22 are independently adjustable, it will be noted that each of the four legs may be adjusted independently of the others. As a result any variationsin the length of the legs or irregularities in the surface on which the trestle is supported may be compensated for by merely adjusting the appropriate clamps.

What I claim as my invention is:

1. A bracket for use in holding a rail and. a pair of supporting legs of a trestle in assembled relationship, comprising a body member having means providing a seat for the rail, U-shaped strapssupported on the body member at opposite sides thereof and cooperating with the body member to slidably receive the upper ends of the supporting legs, clamps respectively supported on the base portions of the U-shaped straps for movement relative to the straps in the direction of length of the legs, said clamps having inwardly extending flanges at the top respectively engageable with the upper ends of the supporting legs and having inwardly projecting flanges at the bottom respectively engageable with the outer sides of the legs to clamp the latter against the body member, and releasable fastening means for respectively securing the clamps to said straps.

2. A bracket for use in holding a rail and a pair of supporting legs of a trestle in assembled The studs 26 relationship, comprising a body member having 7 means providing a seat for the rail, U-shaped straps supported on the body member at opposite sides thereof and cooperating with the body member to slidably receive the upper ends of the supporting legs, clamps respectively supported on the base portions of the U-shaped straps for movement relative to the straps in the direction of length of the legs, said clamps having inwardly extending flanges at the top respectively engageable with the upper ends of the supporting legs and having inwardly projecting flanges at the bottom respectively engageable with the outer sides of the legs to clamp the latter against the body member, releasable fastening means for respectively securing the clamps to said straps, and shoulders provided on the undersides of the top flanges of'the clamps in positions to respectively abut the outer sides of the legs adjacent the upper ends thereof.

3. A bracket for use in holding a rail and a pair of supporting legs of a trestle in assembled relationship, comprising a body member having means providing a seat for the rail, U-shaped straps supported on the body member at opposite sides thereof and cooperating with the body member to slidably receive the upper ends of the supporting legs, clamps respectively supported on the base portions of the U-shaped straps for movementrelative to the straps inthe direction of length of the legs, said clamps having inwardly extending flanges at the top respectively engageable with the upper ends of the supporting legs and having inwardly projecting flanges at the bottom respectively engageable with the outer sides of the legs to clamp the latter against the body member, and releasable fastening means for respectively securing the clamps to said straps, said releasable fastenin means comprisin studs respectively projecting outwardly from the base portions of the straps through slots formed in the clamps and elongated in the direction of movement of the clamps relative to .the straps, and fastener elements respectively threadably engageable with the studs at the outer sides of the clamps. 1

4. A bracket for use in holding a rail and a pair of supporting legs of a trestle in assembled relationship, comprising a body member having means providing a seat for the rail, U-shaped straps supported on the body member at opposite sides thereof and cooperating with the body member to slidably receive the upper ends of the supporting legs, clamps respectively supported on 1 the base portions of the U-shaped straps for movement relative to the straps in the direction of length of the legs, said clamps having inwardly extending flanges at the top respectively engageable with the upper ends of the supporting legs to position the latter vertically relative to the body member, and releasable fastening means for respectively securing the clamps to said straps.

5. A bracket for use in holding a rail and a pair of supporting legs of a trestle in assembled relationship, comprising a body member having means providing a seat for the rail, U-shaped straps supported on the body member at opposite sides thereof and cooperating with the body member to slidably receive the upper ends of the supporting legs, clamps respectively supported on the U-shaped straps for movement relative to the straps in the direction of length of the legs, said clamps having flanges at the top respectively engageable with the upper ends of the supporting legs to position the latter vertically relative to the body member, and releasable fastening means for respectively securing the clamps to said straps.

6. A bracket for use in holding a rail and a pair of supporting legs of a trestle in assembled relationship, comprising a body member having means providing a seat for the rail and having means at opposite sides thereof for respectively slidably receiving the upper ends of the legs, clamps supported by the body member at opposite sides thereof for movement relative to the body member in the direction of length of the legs, said clamps having flanges at the top respectively engageable with the upper ends of the supporting legs to position the latter vertically relative to the body member, and releasable fastening means for respectively securing the clamps to the body member.
